XBee Pulse I/O Single Port 
Assembly Instructions 

Written By: Jordan Husney 



TOOLS: PARTS: 

Solder, lead-freed) XBee Pulse I/O SPv1 BOM. Digi-Key 

Soldering iron (1) Part Number: 6958220-KIT-ND (1) 



SUMMARY 

In this project we're going to assemble the XBee Pulse I/O Printed Circuit Board — an open- 
source hardware design which can be used to automate things wirelessly. This hardware is 
used in the "12,000-mile Universal Remote" project from Make Vol. 30.

Step 1 — XBee Pulse I/O Single Port Assembly Instructions

• Get that soldering iron nice and 
hot! It's time to begin assembly! 

• Begin by soldering in IC1 (the 16- 
pin, 74H123 timer chip). Take care 
to orient the notch in the chip with 
the silkscreen. 

• Next, solder in the five diodes D1, 
D2, D3, D6, D7. Make certain to 
orient the stripe with the stripe on 
the silkscreen. 

• Solder in the NPN transistor T1. 
Match the shape with the 
silkscreen. 

• Finally solder in the 3.3v voltage 
regulator VR1. The metallic heat 
sink on the regulator should be 
oriented with the solid white stripe 
on the silkscreen.

• You're about to solder lots of 
resistors. I think they look like little 
peanuts. Little striped peanuts. 

• All the resistors are oriented on the 
board vertically to save space. 
You'll need to bend the resistor 
leads carefully in order to get them 
to go into the board. 

• Solder on R3 and R5, the 180 ohm 
resistors (brown, gray, brown, 
gold). 

• Next, solder R2, the 1K ohm 
resistor (brown, black, red, gold). 

• Solder R1 and R1 1 , the 1 0k ohm 
resistors (brown, black, orange, 
gold). 

• Finally solder R4, the 18k resistor 
(brown, gray, orange, gold).

Step 3 






• Time for capacitors! 

• Start by solder in the tiny 10pf 
capacitor C4. The capacitor will be 
labelled with an itty-bitty number 
102. You may need a magnifying 
glass to read it. These ceramic 
capacitors have no polarity and can 
be put in the board in any 
orientation. 

• Solder in the 0.01 uF capacitors. 
They will be labelled with a small 
number 104. 

• The next capacitors are electrolytic 
and have a polarity. This means 
they need to be placed in the board 
matching the long leg to the little + 
sign on the board. 

• Solder in the 10uF capacitors C6 
and C9. 

• Solder in the 22uF capacitor C1 . 

• Finally, solder in the 47uF 
capacitor C2. It may be slightly 
larger than the silkscreen outline 
on the board.

• Solder in the LEDs, LED1 and 
LED3. Insert the LEDs so that the 
short pin goes next to the flat line 
on the silkscreen. 

• Solder in the relay K1.

• You're almost done! Time to solder 
the sockets, switch, and terminal 
blocks. 

• Next, solder on the power jack J1. 

• Solder in both of the 10-pin 2mm 
sockets for the XBee. 

• Solder on the tactile switch S1 . It 
doesn't matter how it's oriented. 

• Solder on terminal blocks X1 and 
X3.

• The final step! You must have 
plenty of little bits of wire from all 
the leads you've been snipping off. 
Select two of these wires and bend 
them and insert them as shown into 
the PCB. 

• These wires act as jumpers to 
select the output mode to the relay 
of the XBee Pulse I/O board. 

• All you'll need now is a 5v center- 
positive power supply. You should 
be able to find one from a local 
electronics retailer or from an on- 
line supplier. 

• That's it! You're done! You'll be up 
and pushing buttons from anywhere 
in no time!
